Small apartment with a nice location. Location is really great - Sukhumvit is 5 min by walk, on the street is a nice cafe for breakfasts and lunches, nearby is 21 terminal and big grocery store and BTS / metro station. The apartment building itself is also I think nice - nice hall with a cat (cute), the gym is small but has everything, a swimming pool with a small garden on the top. The pool I thought was a bit dirty, but the view is nice. Also, there was only one sunbed (a bit damaged).
What I didn't like is the air conditioning in the apartment and cleanliness. Regarding the cleanliness - cobwebs and dust on the ceiling (a lot, trust me). Air conditioning is very noisy, you would not be able to put it during the night overwise you would not be able to sleep. Also, the air conditioning was a funny dump smell, and to get rid of it you have to enable it only to the lowest possible temperatures, in this case, the smell would be less tangible. We tried to tell the owner about the smell, and as result, she sent a maid to check who took a picture of the room (with us and all our things inside) and in the end said that the smell was coming from our things...a bit rude we thought
